      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/amd/ras: Fix NULL deref in ras_core_get_utc_second_timestamp()\n\nras_core_get_utc_second_timestamp() retrieves the current UTC timestamp\n(in seconds since the Unix epoch) through a platform-specific RAS system\ncallback and is used for timestamping RAS error events.\n\nThe function checks ras_core in the conditional statement before calling\nthe sys_fn callback. However, when the condition fails, the function\nprints an error message using ras_core->dev.\n\nIf ras_core is NULL, this can lead to a potential NULL pointer\ndereference when accessing ras_core->dev.\n\nAdd an early NULL check for ras_core at the beginning of the function\nand return 0 when the pointer is not valid. This prevents the\ndereference and makes the control flow clearer.",
